MP6551 is an H-bridge motor driver. Its 2.5V to 14V input voltage (VIN) range allows the device to operate from a variety of battery power sources, including single-cell lithium-ion batteries, dual-cell lithium-ion batteries and 3-cell to 6-cell alkaline batteries. Its low on resistance enables it to achieve up to 5A of output current (IOUT) across its entire VIN range. The MP6551 can drive a brushed DC motor in bidirectional applications or two DC motors in unidirectional, speed-controlled applications. Full protection features include overcurrent protection (OCP), undervoltage lockout (UVLO) protection and thermal shutdown. The MP6551 is available in a QFN-14 (2.5mmx3mm) package. Applications include mini drones and battery-powered toys.
